I just recently started to get my 93 200 going again after about three years of sitting. I flushed all fluids, cleaned filter, re-packed silencer, and put in new plug. I have burned out all of the old gas/oil in the carb. I have not actually ridden it after this, but during start/running, I am getting excessive smoke. I have tried to burn it out by gassing it a bit, but it still smokes like a chimney. Did not do this prior to parking the bike. What gives? Should I worry?
